INKING MECHANISM FO'R' PRINTING PRESSES.

T 0 all whom it may concern Be it known that we, EDWARD R. LINE BAUGHand MARTIN I-I. STENDER, citizens of the United States, and residents ofBarberton, in the county of Summit and State of Ohio, have inventedcertain new and-useful Improvements in Inking Mechanism for PrintingPresses, of whichthe following is a specification.

This invention relates to inking mechanism for printing presses, andmore especially the kind of presses wherein associated inking-anddistributor rollers arecooperatively arranged in relation to anink-distrib uting disk and a type form. In presses of the kind mentionedthe distributor roller is mounted to rotate in peripheral contact with apair of inking rollers, and the associated rollers are borne by aswinging frame which is so constructed and arranged as to carry therollers through a path wherein the inking rollers travel'upon the typeform and the inking surface of the disk. The distributor roller hascombined therewith screw and nut mechanism which is constructed andactuated to impart a single longitudinal impulse to the roller duringeach succeeding stroke of the associated rollers in order to effect thedistribution of the ink on the peripheries of the inking rollers. Suchmechanism is expensive; it requires nice fitting and adjustment, and itsoon gets out of order.

The object of our invention is to'provide a motion' transmittingmechanism of simple and eflicient construction between the swingingframe and the'distributor roller, whereby several longitudinal impulsesare imparted to the distributor roller during each succeeding stroke ofthe frame, and in consequence a better distribution of the ink on theinking rollers than formerly is accomplished,

as will be hereinafter described and claimed.

In the drawings Figure 1 is a side elevation, partially in dottedoutline, of a portionof a style of printing press equipped with inkingmechanism embodying the principle of our invention.

Fig. 2 is an enlarged view of one end of the associated ink distributorand inking rollers, and their connections with the swinging frame.

Fig. 5 is a longitudinal-section of one end Ofthe distributor roller andof its shaft, showing one of the adjustable end stops for Fig. 6 is aperspective view of the distr-ibu tor roller and its shaft.

Fig. 7 is a similar viewofone end of the associated rollers and; theirsupporting saddle, showing the bell-crank connection which is includedin the mechanism for reciprocating the distributor roller.

Referring to the drawings, 10 designates the stationary main frame ofatypical printing press, and 11 the oscillatory bed frame thereon, whichlatterframe supports the type-form at 12; and also the relatively inclined ink-distributing disk 13 and the inking devices and theirappurtenances. Such inking devices include an ink fountain 14 arrangedto overhang the upper path of the disk; a'roller 15 for said fountain; apair of inking rollers 16; a distributor r0ller'17 in peripheralcontactwith the latter, a nda single inking roller 18 below'the roller16. The V rollers 16' are borne in spaced parallel relation to eachother by saddles 19 which are located at each side of the press. Eachsaddle is pivotally connected to the outer end of a longitudinallyreciprocative rod 20 that is slidably mounted on the adjacent sideinember 21 of a. swinging frame pivotally supported on the bed frame 11.Only one of the saddles and its operating. rod are shown. The lowerroller 18 is supported at each end by a hook saddle 22 which is alsoconnected with a reciprocative rod 23 mounted in the adjacent framemember 21. The rods 20, 23

are normally retracted by means of suitably disposed springs, as 24,thereon, and the various elements are so co-operatively arranged thatduring the oscillation of the frame 21 the respective saddles and theirrollers 'are swungupwardly and rearwardly and back again 1n such amanner that the inking rollers traverse the type-form and V the inkingsurface of the disk. The upper roller. of the pair as it reaches thelimit of its rearward movement impinges against the fountain roller 15and takes ink therefrom, which ink in the next su'cceedingforwardmovement of the frame 21 and its accessories is transferred to therollers 16, which, in turn, distribute the ink on the surface of thedisk.

In the oscillatory travel of the roller-car rying frame 21 the inkingrollers are maintained in yielding contact with the opposing type-formand with the inking surface of the disk, by the retractive force of thesprings on the respective rods 20, said rods being longitudinally movedin the respective frame members in accordance with the varying outwardand inward distances of the rollers in respect to the axis ofoscillation of the frame. The foregoing described mechanism beinggenerally old, it requires no detailed description herein.

In the preferred form of our invention herein illustrated thedistributor roller 17 is loosely mounted on a shaft 25 having at eachend a polygonal end portion 26 which is mounted in a bearing bracket 27on the adjacent saddle 19. The roller 17 is adjustably positioned forrotation on the shaft by end stops comprising split screw heads 23 whichare clamped on the shaft and at the respective ends of the roller bymeans of nuts 29 on the heads. The bracket 2? has an openingtherethrough which receives the end portion of the shaft, such openingbeing of appropriate size and form to permit movement of the shafttransversely as well as longitudinally of its axis. In the bracket is asuitably-disposed plunger 30 which is pressed against the opposed shaftportion 26 by the confined spring 31, the distributor roller thus beingheld yieldingly in peripheral contact with the inking rollers 16. Oneend of the shaft is provided with a bifurcated member 32 which embracesan arm 33 of a bell-crank lever and thus constitutes a. lever engagingmen'iber. This lever is fulcrumed, as at 34:, on a block member 35 looseon an elongated pivot stud 36 which connects the adjacent saddle 19 withits rod 20, Loose on the stud is one end of link 37 which is pivotallyconnected at its op posite end to a rock-ar1n 38, fulcrumed, as at 39,on. the adjacent frame member 21. The rock-arm is connected by means ofa link with the other arm, ll, of the bellc-rank lever, which link ispreferably made in two parts adjustabl y connected. by means of a screwturn-buckle 42.

The foregoing described lever and link connections constitute motiontransmitting mechanism between the swinging frame and the distributorroller, whereby, during the effective travel of the said frame and theresulting longitudinal reciprocation of the rod 20 having the elongatedstud connection with the adjacent saddle 19, the rock-arm 38 isoscillated and the motion is positively transmitted therefrom by meansof the link 4&0 to the crank-lever, which lever, in turn, effectslongitudinal reciprocation of the distributor 1,495,eoe

roller upon the peripheries of the inking rollers 16. Owing to thevarious longitudinal movements of the rod 20 during its travel with theframe member 21 several recipr cative impulses of the distributor rolleralong the inking rollers are effected, such impulses, in theconstruction illustrated, being four times as often as when thedistributor roller is moved by the screw and nut devices previouslyemployed, and, in consequence, a better distribution than formerly ofthe ink is ensured, which result is particularly desirable on jobsrequiring heavy ml:- ing.

It is to be noted that the acting arm of the bellcrank lever is maderelatively broad to ensure its continued effective engagement with thebifurcated member 32 at various points and thus compensate for thedifferent angular positions assumed by such arm and the rollerbearingsaddle during their travel with the frame 21.

Our invention is not limited to the specific details of constructionherein disclosed as the mechanism may be modified within the principleof the invention and the scope of the appended claims.
